### Features

* discovery-based APIs and pagination (#2350)
([cb21cf1](cb21cf1))

* Make generated `ProtoMessage` and `ProtoEnum` classes `final` (#2349)
([7d0520b](7d0520b))

* Require that all imports have a version contraints (#2331) Fixes #1989

This should not be landed before
googleapis/google-cloud-rust#3396
([00828d5](00828d5))

* Generate samples for single value setters (#2263)
([f7c0b84](f7c0b84))

* discovery doc arrays (#2337)
([da69195](da69195))

* Inject InstrumentationClientInfo for tracing (#2252) - Add static
INSTRUMENTATION_CLIENT_INFO to lib.rs.mustache.
- Use INSTRUMENTATION_CLIENT_INFO in transport.rs.mustache if tracing is
enabled.

For #2212 see also
googleapis/google-cloud-rust#3347 and
googleapis/google-cloud-rust#3376
([1358226](1358226))

* parse most object fields (#2318) Parse most fields of object in a
discovery doc. Fields with an inline
type definition still need some custom work.
([f2d1a10](f2d1a10))

* Add the ability to insert text after the package title (#2323) The
current use case for this is to advise users of equivalent Firebase
packages. For example:

```toml
readme-after-title-text = &#34;&#34;&#34;&gt; [!TIP]
&gt; Flutter applications should use [Firebase AI Logic](https://firebase.google.com/products/firebase-ai-logic).
&gt;
&gt; The Generate Language API is meant for Dart desktop and cloud applications.
&gt; Firebase AI Logic provides client-side access to both the Gemini Developer
&gt; API and Vertex AI. &#34;&#34;&#34;
```

Which results in a README.md that looks like:

&lt;img width=&#34;1485&#34; height=&#34;909&#34; alt=&#34;image&#34;

src=&#34;https://github.com/user-attachments/assets/a1c9120e-eafd-4394-9562-48c595ab4960&#34;
/&gt;

### Bug Fixes

* read version from version.txt file (#2347) Fixes #2348

Moves version.txt to the `internal/cli` package so it can be read by the
`embed` package as a variable.
When constructing the synthetic version number, use this release version
as the base.
([014b5f4](014b5f4))

* race condition in createWorkRoot() (#2338) Creating a temporary
directory based on a timestamp is inherently racy.
Use the standard functions to create temporary directories, and relax
the tests to check for what matters.
([46428ca](46428ca))

* parse github remote from local directory (#2328) Fixes #2327
([1c71bd9](1c71bd9))
